Draw in detail the waveform at the output (Vo) of the circuit in Figure 2. Then obtain the maximum current flowing through the Zener diode. Consider that all diodes (including the Zener) behave like direct bias Silicon diodes. For reverse bias the Zener voltage is 8.6 V; all other diodes never conduct in reverse bias. The input voltage is a 1 Hz triangular signal with values from -20V to 20V.

Ctri Question 3 (20 Marks) Lab 1-Zener Circuits and Applications Theory: Zener diode is designed to operate in reverse conduction. Zener breakdown occurs at a precisely defined voltage, allowing the diode to be used as a voltage reference or clipper. While Zener diodes are usually operated in reverse conduction, they may also be operated in cutoff and forward conduction. There are two different effects that are used in "Zener diodes". The only practical difference is that the two types have...
